BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stick-shaped cosmetic container such as a lipstick, and more particularly to a plug-in type stick-shaped cosmetic container, and more particularly to an improvement in a structure for preventing the stick-shaped cosmetic from falling off due to an impact.

[0002]

2. Description of the Related Art A stick-shaped cosmetic such as lipstick has a base end held and stored in a dish portion, and is used or stored in a container by moving the dish portion in and out.

By the way, when an impact is applied to the container such as when the container is dropped, the vibration caused by the impact is propagated to each part of the container,
As a result, binding of the stick-shaped cosmetic to the dish may be released, and the stick-shaped cosmetic may fall off the dish. In particular, since unused or early-use bar-shaped cosmetics have a larger portion protruding to the outside than a portion held and stored in the dish, they tend to fall off the dish when an impact is applied.

Therefore, it is necessary to prevent such falling off. For example, a structure is conceivable in which a spring is attached below the dish portion and fixed by a metal ring or the like to absorb vibration due to impact.

[0005]

However, since this kind of container is small and has a large number of parts, the number of parts increases in the above-described structure, and as a result, the assembly becomes complicated. .

[0006] The spiral cylindrical rod-shaped cosmetic container according to the present invention solves the above-mentioned drawbacks, and aims to prevent the falling off of the rod-shaped cosmetic from the inner plate with a relatively small number of parts and a structure that is easy to assemble. And

[0008]

When the vibration due to the impact propagates to the inner plate, the inner plate presses the spring and absorbs the impact force by the contraction of the spring. For this reason, the stick-shaped cosmetic held and stored in the plate portion of the inner plate body is not subjected to vibration due to impact, and the stick-shaped cosmetic does not fall off the plate portion.

Further, since the inner plate is structured to hold the spring, the number of parts is relatively small, and assembly and disassembly are easy.

Reference numeral 19 denotes a middle plate body, which is composed of a plate portion 21 for accommodating the stick-shaped cosmetic material 5, and legs 23 connected to the plate portion 21. The inner plate 19 is integrally attached to the center shaft 13. That is, the leg 23 is composed of a pair of rod-shaped members that are continuous from the ends located on symmetric points on the bottom surface 25 of the dish 21, and holds the spring 27 urged in the direction of the dish 21.
On the other hand, a notch 29 is provided in the upper part of the center shaft 13 along the axial direction, and the legs 23 are fitted into the notch 29. In the drawing, 31 is the upper surface of the center shaft 13, 23a is a locking portion of the leg 23, and 21a is a cut formed in the dish 21. Reference numeral 33 denotes an inner tool mounted between the hakama cylinder 17 and the outer cylinder 9. The center shaft 13 is desirably formed to have a thickness of about 0.2 mm to about 0.5 mm when made of metal, and about 0.3 mm to about 1.0 mm when made of resin.

The method of assembling the spiral cylindrical stick-shaped cosmetic container according to the present invention is as follows. First, a spring 27 is inserted from the bottom surface side of the center shaft 13 (the right side in FIG. 1), and in this state, the plate portion 21 of the center plate body 19 is fitted into the cutout portion 29 of the center shaft 13,
It is an integral jig.
